TANNING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 716,358, datedDecember 23, 1902.

Application filed February 27,1902. Serial No. 95,956. (No model.)

To aZZ whom it may concern:

Be it known that we, BONA ALLEN, Jr., and WILLIAM G. ALLEN, citizens ofthe United States, residing at Buford, in the county of Gwinnett andState of Georgia, have invented certain new and useful Improvements inApparatus for Tanning; and we do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to improvements in apparatus for tanning hides,skins, and, the

like, and has for its object to provide a revoluble tanning-wheel,certain features of novelty of which will hereinafter appear.

In order to more fully set forth our said invention, reference will behad to the accompanying drawings, wherein- Figure 1 represents atransverse sectional view on the line 1 1, Fig.2. Fig. 2 is a plan viewof an apparatus for tanning constructed in accordance with ourinvention. Fig. 3 is a transverse sectional view on the line 3 3 of Fig.4, and Fig. 4 is aplan view of a modified form of our invention.

In the drawings, A represents the tanningvat, adapted to be filled up tothe water-line (indicated in Figs. 1 and 3) with tanning liquor.

B represents a shaft mounted in bearings C O on the stationary standardsD D, preferably located upon the outside of the vat. This shaft B runslongitudinally of the vat, suitable packing or other means beingprovided at the points where said shaft passes through the sides of thevat to prevent leakage of the tanning liquor, which completely submergesthe shaft.

E is a hollow drum rigidly mounted upon the shaft B, so as to rotatetherewith. Into this drum E is placed the solid extract, access beinghad to the interior of this hollow drum through the door F, mounted uponthe hinges G G in the periphery H of said drum, the said hinged doorbeing held closed by means of the cotter I, passed through the eyeboltsJ and the lug f upon the door F. Perforations h 72 are provided in theperiphery H of this drum E, to allow the free entrance and exit of thetanning liquor to the solid extract for maintaining the strength of theliquor in the vat. Upon the opposite end of the shaft B is rigidlymounted the cross-arm K, the arms of which extendout radially from theshaft. These arms are perforated, so as to each receive a plurality oflongitudinally-dis posed bars L, said bars being in groups extending outradially from the shaft. The opposite ends of these bars L arepreferably'secured in perforations in the side of the drum E, suchperforations corresponding with the perforations in the cross-arms K;but, if preferred, a second cross-arm similar to the cross-arm K maybeemployed upon the op posite end of the shaft B, adjacent the drum E, forsupporting the ends of the bars L. A pulley M is preferably mounted uponone end of the shaft 13 outside of the vat, by means of which power maybe applied to rotate the shaft.

Upon the radially-arranged bars L are hung the doubled hide or skin tobe treated, any number of such hides being thus hung at one time. Duringthe rotation of the shaft each hide will assume a position similar tothe hide N, (indicated in dotted lines in Fig. 1,) and so it will beseen that the hides being entirely submerged the action of the liquorwill be uniform upon the same and the entire surface of each hide willat all times be fully exposed to the action of the tanning or otherliquor, the objectionable feature of the hides lapping upon each otherbeing entirely eliminated.

In Figs. 3 and 4.- we have shown amodified form of the apparatus inwhich we dispense entirely with the solid-extract drum H, a liquidextract or other tannin which would not have to be melted being used. Inthis construction we have also dispensed with the cross-arms K and haveprovided the two disks or drum-heads O, in which the hide-bars L areheaded or otherwise secured, and instead of arranging the hide-bars inradially-disposed groups, as shown in Figs. 1 and 2, the bars of eachgroup are arranged in a plane out of line with the shaft B. Although wehave only shown this construction as applied to the modificationillustrated in Figs. 3 and at, it is obvious that in the apparatus shownin Figs. 1 and 2 the cross-arm K could be omitted and this latterarrangement of the hide-bars substituted. It is also obvious thatalthough We have only shown a single wheel in .the vat we can andusually do construct a vatof sufficient dimensions and divided off intocompartments to contain a series of tanning-wheels, each compartmentcontaining tanning liquor of different strength, so that when a freshpack of hides are put in they are first given the Weakest liquor andthen the next strongest, and so on until the pack is tanned. It is alsoobvious that many modifications might be made without departing from thespirit of our invention; but

What we claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In an apparatus for tanning, the combination with a vat, of atanning-Wheel, rotatably mounted in said vat, provided with a group oflongitudinally-disposed hide-supporting bars, the bars of said groupbeing arranged in a series extending inwardly from the periphery of thewheel, and means for rotating said wheel.

2. In an apparatus for tanning, the combination with a vat, of atanning-wheel rotatably mounted in said vat, comprising end supports andgroups of hide-supporting bars connecting said end supports,the bars ofeach group being arranged in series extending inwardly from theperiphery of the Wheel, and means for rotating said tanning-wheel.

3. In an apparatus for tanning, the combination with a vat, of atanning-wheel rotatably mounted therein and provided with a group oflongitudinally-disposed hide-supporting bars, the bars of said groupbeing arranged in an alined series extending inwardly from the peripheryof the Wheel, and means for rotating said Wheel.

4. In an apparatus for tanning, the combination with a vat, of arotatable shaft passing through said vat, a hollow perforated drumcarried by said shaft, a support carried by said shaft, and groups ofhide-supporting bars carried by said support and running longitudinallyof the shaft, and means for rotating said shaft.

5. In an apparatus for tanning, the combination with a vat, of arotatable shaft passing through said vat, a hollow perforated drumcarried by said shaft, a cross-arm upon said shaft, and groups ofradially-arranged bars carried by said cross-arm.

6. In an apparatus for tanning, the combination with a vat; andstationary bearings adjacent the ends of said vat; of a rotatable shaftmounted in said bearings and passing longitudinally through said vat, ahollow perforated drum carried by said shaft, and hidesupporting barscarried by said shaft.

7. In an apparatus for tanning, the'combination with a vat, of a shaftrotatably mounted therein, a cross-arm carried by said shaft, groups ofhide-supporting bars carried by said cross-arm and disposedlongitudinally of said shaft, the bars of each group being arranged in aseries extending radially along the arms of said cross-arm, and meansfor rotating said shaft.

8. In an apparatus for tanning, the combination with a vat; of arotatable shaft passing longitudinally through said vat, a hollow drummounted upon said shaft, provided with a plurality. of perforations inits periphery, a hinged door in said drum, and means carried by saidshaft for supporting the hides.

9. In an apparatus for tanning, the combination with a vat; of alongitudinally-disposed shaft passing through said vat, a hollow drumprovided with a plurality of perforations in its periphery, mounted uponsaid shaft, a hinged door communicating with the interior of said drum,a cross-arm carried upon the opposite end of said shaft, andhidesupporting bars arranged in radial groups, supported in openings insaid cross-arms and drum.

In testimony whereof We affix our signatures in presence of twowitnesses.
